Quantum technology taken to its (speed) limit
Prof. Dr. Tommaso Calarco (Institut für Quanten-Informationsverarbeitung, Universität Ulm)


Quantum effects form the basis of most present-day information technologies, from electronics to optical telecommunications. However, the full power of quantum coherence has not yet been tapped for everyday technological applications. The exquisite level of control of current atomic physics experiments may enable this, for instance in the field of quantum communication and quantum computing - but scalable quantum information processing requires extremely precise operations. Quantum control theory allows to design the evolution of realistic systems in order to attain the best possible performance that is allowed by the laws of quantum mechanics. I will present a range of its applications to a variety of quantum technologies, and discuss its use in probing the ultimate limits to the speed of the corresponding quantum processes.
